Abstract

Abstract Description of the subject: Lavandula stoechas L. (Lamiaceae) is an attractive shrub native to the Mediterranean regions, this species presents an increasing interest in medicine, cosmetics and for preserving and improving the flavor of foods. Objective : This study aims to investigate the essential oil (EO) composition and biological activities (antibacterial, antifungal and antioxidant) of the essential oil of Lavandula stoechas cultivars in Algeria. Methods : Lavandula stoechas essential oil, obtained from plants grown in the North of Algeria, was gathered, dried, hydrodistilled and their essential oil analyzed by gas chromatography coupled with mass spectrometry (GC-MS). allowing to obtain qualitative and quantitative results of Lavandula stoechas. This characterization was completed with different biological activities. Results : Fifty compounds were identified, four of them (fenchone, camphor, lavandulyl acetate and cineole) accounting for more than 60% of the total oil in the analyzed samples. Antioxidant activity was evaluated positively by DPPH method. The antimicrobial activity revealed that Lavandula stoechas essential oils are inhibitory against the tested bacteria and fungal strains. Conclusion : These properties support the potential use of L. stoechas EO as natural cosmetic and natural pharmaceutical ingredients for several skin diseases.
